If you’re looking for a dish that’s both hearty and bursting with fresh, savory flavors, then look no further than these Caprese Stuffed Garlic Butter Portobellos. The earthy portobello mushrooms serve as the perfect base, loaded with a rich and garlicky butter sauce, and then stuffed with a delightful Caprese-inspired filling of juicy tomatoes, melty mozzarella, and fresh basil.

  • 4 large portobello mushrooms, stems removed, cleaned
  • 4 tablespoons unsalted butter, melted
  • 4 cloves garlic, minced
  • Salt and pepper, to taste
  • 1 cup cherry tomatoes, halved
  • 1 cup fresh mozzarella, shredded or in small chunks
  • 1/4 cup fresh basil, chopped
  • Balsamic glaze, for drizzling (optional)

1. Preheat the Oven

Preheat your oven to 375°F (190°C). Line a baking sheet with parchment paper for easy cleanup.

2. Prepare the Mushrooms

Remove the stems from the portobello mushrooms and gently clean the caps with a damp paper towel. Be sure to scrape out the gills with a spoon, creating a nice well to hold the stuffing.

3. Make the Garlic Butter

In a small bowl, melt the unsalted butter and then stir in the minced garlic. Add salt and pepper to taste. This garlic butter mixture will be used to brush on the mushrooms, giving them a rich, flavorful base.

4. Prepare the Caprese Filling

In a separate bowl, combine the cherry tomatoes (halved), fresh mozzarella, and chopped fresh basil. This mix brings the fresh flavors of a Caprese salad right into the heart of your portobello mushrooms.

5. Stuff the Mushrooms

Place the cleaned mushroom caps on the prepared baking sheet. Use a spoon to brush the tops and bottoms of the mushrooms with the garlic butter mixture, ensuring they are well-coated. Then, generously stuff each mushroom cap with the Caprese mixture, pressing gently to pack the filling in.

6. Bake

Place the stuffed mushrooms in the preheated oven and bake for 15-20 minutes, or until the mushrooms are tender and the cheese is melted and bubbly. The garlic butter will infuse the mushrooms, making them flavorful and aromatic.

7. Drizzle with Balsamic Glaze (Optional)

Once the mushrooms are baked, remove them from the oven and drizzle with balsamic glaze for an added touch of sweetness and acidity. It’s completely optional, but highly recommended for a burst of extra flavor.

8. Serve and Enjoy

Serve the Caprese Stuffed Garlic Butter Portobellos warm as a main dish or appetizer. These mushrooms pair wonderfully with a light salad or pasta for a well-rounded meal.

  • Cheese Options: If you prefer a different cheese, fresh burrata or provolone would work well in place of mozzarella.
  • Balsamic Glaze: The balsamic glaze adds a sweet tanginess that complements the savory flavors of the mushrooms. You can also make your own by reducing balsamic vinegar in a saucepan until it thickens.
